ACETYLENE-GAS APPARATUS.

SPECIFICATION forming part of Letters Patent N0. 663,771, dated December11, 190

Applicatio fil d March 28, 1900. semi No. 10,538. on model.)

To all whom, it may concern:

Be it known that I, FREDERICK METZGER, a citizen of the United States,and a resident of Hondo, in the county of Medina and State of Texas,have invented a new and Improved Gas-Machine, of which the following isa full, clear, and eXact description.

This invention relates to improvements in gas-machines in which the gasis generated from calcium carbid; and the object is to provide a machineof simple construction in which there can be no loss or leakage of gasand in which the gas will be thoroughly washed before passing to thedistributing-pipe, thus affording a pure white light, and, further, toprovide a means for running off coal-tar that may gather on the top ofthe water in the machine.

I will describe a gas-machine embodying myinvention and then pointoutthe novel features in the appended claim.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar characters of reference indicatecorresponding parts in both the figures.

Figure 1 is a sectional elevation of a gasmachine embodying myinvention,and Fig. 2 is a horizontal section thereof.

Referring to the drawings, 1 designates the body portion of the machine,and 2 the bell, movable therein. Extended upward from the bottom of thebody portion 1 is the generating-cylinder 3, surrounded by a jacket 4,attached to the upper wall of the .bell2, and

between this jacket 4 and the cylinder 3 is a.

water-space providing a water seal. The jacket 4 extends somewhat abovethe top wall of the bell 2 and is provided with a cover 5, held tightlyin place by a bar 6 engaging with the top of the cover and having itsends engaging with hook-plates 7, attached to the top of the bell.

Suspended within the cylinder 3 is the basket 8 for containing thecalcium carbid. From the bottom of the cylinder 3 a pipe 9 leads outwardand communicates with a discharge-pipe 10. This pipe 9 is designed tocarry ofl. water and ashes that may gather in the generating-cylinder,and to prevent an escape of gas therethrough the said pipe 9 is providedwith a valve 11. A gas-pipe 12 communicates with the interior of thejacket 4 near the top and extends downward into the water contained inthe machine, nearly to the bottom thereof, as plainly indicated in thedrawings. This pipe 12 is shown as communicating with a hood 12, whichsupports the basket and prevents pressure on the cover 5, and the lowerend of the pipe 12 is provided with a valve 12", preventing the entranceof water, but permitting outflow of gas. The hood 12 is supported byasection of the pipe 12, extended into the jacket. As shown, the hood hasa short pipe-section provided with a flange removably connected by boltsor otherwise to a flange on the end of the pipe 12; but this hood may beomitted, if

desired, and in such case the basket will be supported from a hook onthe inner side of the cover 5.

At one side of the body portion 1 is a waterpipe 13, which hascommunication at 14 with the body portion and also connects at the lowerend with a pipe 15, which is extended into the generating-cylinder 3,where it is provided with a gooseneck 16 to prevent its becoming cloggedwith falling ashes of the carbid. ,The pipes 13 and 15 are designed tosupply water from the body portion of the machine to the interior of thecylinder 3, and the pipe 13 is provided near the lower end with aplug-valve 17. Connected to the hell 2 and extended into the pipe 13 isa pipe or rod 18, which serves as a guide for the vertical movement ofthe bell. The guide at the opposite side consists of a blow-0E pipecomprising a member 19, extended downward into the bell, and a member20, extended into a tube 21, attached to the body portion of the machineand communicating with the discharge-pipe 10 through a pipe 22,connecting with thelower end of the pipe 21. The pipe 20 may be causedto fit gas-tight in the pipe 21 by a packing of tallow or the like.

A pipe 23 for the discharge of scum that may gather on the top of thewater in the machine extends upward in the body portion and has afunnel-shaped top 24. This pipe 23 communicates at its lower end withthe pipe 10 through a pipe 25, in which .a vaive 26 is placed. Agas-service pipe 27 extends upward in the machine, having itsfunnelshaped upper end above the water-level and provided with a netting28. This pipe 27 '32, which extends through the top wall of the bell 2and has a funnel-shaped inner end, in which is arranged a netting 33.Either one or both of the pipes 27 and 32 may be utilized for thedistribution of gas generated by the machine.

In operation water is to be poured into the machine through, a feed-pipe34:, extended through the top wall of the bell 2 and nearly to thebottom of the machine. As the water reaches the tube 14 it will passthrough the pipes 13 and 15 and the gooseneck 16 into thegenerating-cylinder 3. The carbid in the basket 8 will be immersed inthe water, and as the gas generates it will pass through the pipe 12 andthence upward through the water, becoming thoroughly Washed. As the bellrises the carbid will be carried more or less out of the water, stoppingto a great extent the generation of gas.

Shouldan excessive pressure'occur or a sufficient amount of gas begenerated to raise the bell, bringing the lower end of the escapepipesection 19 above the level of the water, the gas will pass out throughthe escape-pipe 10, which may lead to any suitable point.

Having thus described my invention, I claim as new-and desire to secureby Letters Patent- A gas-machine, comprising a body portion, a bellarranged therein, a pipe extended down at one side of the body portionand having communication with said body port-ion near the top, acylinder arranged within the body portion,a pipe leading from said bodyportion into the cylinder, a guide-rod attached to the bell and extendedinto said pipe, a blow-oft pipe attached to the bell, a pipe fixed tothe body portion and in which the outer member of said blow-off pipe ismovable, thus forming a guide for the bell, a carbid-holder in thecylinder,

a gas-discharge pipe leading from the body portion, a gas-discharge pipeleading from the generator-cylinder, nearly to the bottom of the bodyportion, and a check-valve in the lower end of said gas-pipe,substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

FREDERICK METZGER.
